Rambam-Hasharon syndrome of psychomotor retardation, short stature, defective neutrophil motility, and Bombay phenotype.
We describe 2 Arab patients, both offspring of unrelated consanguineous matings, with unusual facial appearance, severe mental retardation, microcephaly, cortical atrophy, seizures, hypotonia, dwarfism, and recurrent infections with neutrophilia. Neutrophil motility was markedly decreased but the opsonophagocytic activity was normal. Both patients lack the red blood cell (RBC) H antigen and manifest the Bombay (hh) phenotype. Familial endocardial fibroelastosis and familial tetralogy of Fallot segregated independently in one family. The occurrence of the same syndrome in 2 unrelated families suggests that the various aspects of the disorder are the pleiotropic effects of a single mutation. Homozygosity-by-descent for a deletion involving contiguous genes may explain the findings in this syndrome. Alternatively, a mutation which involves an ubiquitous GDP fucose donor rather than the enzyme (alpha 2-L-fucosyltransferase) or its substrate (glcNAc) may account for the pleiotropic manifestations in this syndrome.

Mumps-associated acute cerebellar ataxia.
During a mumps outbreak between 1987 and 1988, six children presented with symptoms of acute cerebellar involvement as the sole neurologic complication. The neurologic symptoms followed parotitis and lasted for up to 3 weeks. Serologic evidence was suggestive of recent mumps infection. Symptoms spontaneously resolved in all patients without any residual signs or symptoms during 2- to 2.5-year follow-up.

Ataxia-telangiectasia: linkage analysis in highly inbred Arab and Druze families and differentiation from an ataxia-microcephaly-cataract syndrome.
Ataxia-telangiectasia (A-T) is a progressive autosomal recessive disease featuring neurodegeneration, immunodeficiency, chromosomal instability, radiation sensitivity and a highly increased proneness to cancer. A-T is ethnically widespread and genetically heterogeneous, as indicated by the existence of four complementation groups in this disease. Several "A-T-like" genetic diseases share various clinical and cellular characteristics with A-T. By using linkage analysis to study North American and Turkish A-T families, the ATA (A-T, complementation group A) gene has been mapped to chromosome 11q23. A number of Israeli Arab A-T patients coming from large, highly inbred families were assigned to group A. In one of these families, an additional autosomal recessive disease was identified, characterized by ataxia, hypotonia, microcephaly and bilateral congenital cataracts. In two patients with this syndrome, normal levels of serum immunoglobulins and alpha-fetoprotein, chromosomal stability in peripheral blood lymphocytes and skin fibroblasts, and normal cellular response to treatments with X-rays and the radiomimetic drug neocarzinostatin indicated that this disease does not share, with A-T, any additional features other than ataxia. These tests also showed that another patient in this family, who is also mentally retarded, is affected with both disorders. This conclusion was further supported by linkage analysis with 11q23 markers. Lod scores between A-T and these markers, cumulated over three large Arab families, were significant and confirmed the localization of the ATA gene to 11q23. However, another Druze family unassigned to a specific complementation group, showed several recombinants between A-T and the same markers, leaving the localization of the A-T gene in this family open.

Autosomal recessive blepharophimosis, ptosis, V-esotropia, syndactyly and short stature.
A recessively inherited syndrome of blepharophimosis and ptosis with weakness of extraocular and frontal muscles is reported in six members of three related kindreds. Prognathism, synophrys and thick eyebrows added to a typical facial appearance. Additional findings included short stature, borderline head circumference and toe syndactyly. Borderline mental retardation and anosmia were found in one patient. The clinical features and the mode of inheritance distinguish this syndrome from other blepharophimosis and ptosis syndromes.

Transverse myelitis following mumps in children.
Although acute transverse myelitis is a rare complication of mumps, it is relatively well documented. We describe a child who developed mumps associated acute transverse myelitis and who subsequently recovered completely. To our knowledge, only 13 cases have been reported in children. This case is compared with 13 previously reported patients.

The general intelligence and spatial abilities of gifted young Belgian chess players.
Thirty-three tournament-level young Belgian chess players aged 8 to 13 were tested with the French WISC (Wechsler Intelligence Scale for Children). The mean full scale IQ = 121, verbal IQ = 109 and performance IQ = 129. The results suggest that a high level of general intelligence and of spatial ability are necessary to achieve a high standard of play in chess. The high spatial ability of these young chess players suggested by the high performance IQs may go some way towards explaining why males tend to be more numerous than females among high-standard chess players.

Postcircumcision urinary tract infection.
The possible association of urinary tract infection (UTI) with ritual circumcision on the eighth day of life was studied by analyzing the epidemiology of urinary tract infections during the first year of life in 169 children with UTI (56 males and 113 females) born in Israel from 1979 to 1984. Forty-eight percent of the episodes of UTI occurring in males appeared during the 12 days following circumcision, and the increased incidence during that period was highly significant. The median age of the males at the time of the UTI was 16 days, compared with seven months in females. Ritual Jewish circumcision as practiced in Israel may be a predisposing factor for UTI during the 12-day period following that procedure.

Fixed drug eruption of the scrotum due to methylphenidate.
OBJECTIVE: To report two cases of fixed drug eruption induced by methylphenidate. CASE SUMMARY: Two children with attention deficit disorder treated with methylphenidate as a simple drug developed fixed drug eruption of the scrotum. Drug discontinuation was followed by a complete resolution of the skin eruption. Rechallenge resulted in the same drug rash. Macrophage migration-inhibiting factor (MIF) assay with methylphenidate was positive. DISCUSSION: The pathogenesis of fixed drug eruption and the role of MIF assay in the diagnosis of adverse drug reaction is discussed. CONCLUSIONS: Fixed drug rash induced by methylphenidate is a possible but rare phenomenon.

The autosomal dominant polycystic kidney disease gene in a Jewish family from Uzbekistan is PKD1.
A large Jewish family from Tashkent (Uzbekistan) was studied for linkage of autosomal dominant polycystic kidney disease (ADPKD) to molecular markers on the short arm of chromosome 16. A restriction fragment length polymorphism (RFLP) analysis was performed on 28 family members, including 9 ADPKD diagnosed patients in 3 consecutive generations. A specific haplotype was found to segregate with the disease in eight of the nine affected individuals. The peak lod scores for linkage between the disease phenotype and the five informative flanking markers were: 3'HVR 1.70 at theta = 0.08; GGG1 1.18 at theta = 0.001; CMM65 1.50 at theta = 0.001; 26-6 0.86 at theta = 0.001 and 218EP6 1.39 at theta = 0.001. A particular haplotype of these markers segregated with the disease phenotype. The peak lod score of this haplotype was 3.046. Homogeneity test, comparing this family to 40 PKD European families, showed that the conditional probability that it belongs to the same group is 1.000. Taken together, these findings show that the defective gene in this Jewish family from Uzbekistan is PKD1. To our knowledge, this is the first ADPKD family in Israel in whom linkage studies were performed and one of the few originating from populations outside the Western world.

Autosomal recessive Peters anomaly, typical facial appearance, failure to thrive, hydrocephalus, and other anomalies: further delineation of the Krause-Kivlin syndrome.
Two cousins and an unrelated patient, all offspring of consanguineous parents, presented with Peters anomaly, unusual facial appearance, disproportionate short stature, retarded skeletal maturation, and a variable degree of mental retardation. Variable digital, cardiac, CNS, and urogenital anomalies were present. The inheritance is probably autosomal recessive. The condition is a distinct clinical entity for which we suggest the eponym Krause-Kivlin syndrome. Peters anomaly is thought to result from abnormal migration of neural crest cells. A similar mechanism was implicated in the pathogenesis of other disorders of the anterior chamber. The presence of Peters anomaly, and possibly of other corneal endothelial disorders in a newborn infant, should alert the clinician to the possibility of this syndrome. Communicating hydrocephalus (or brain atrophy) and polyhydramnios were documented in two patients, potentially allowing prenatal diagnosis in secondary familial cases.

The ATC (ataxia-telangiectasia complementation group C) locus localizes to 11q22-q23.
The multisystem autosomal recessive disease ataxia-telangiectasia (A-T) is determined by several genes, as evidenced by the existence of four complementation groups in this disorder. Using linkage analysis, the ATA (A-T complementation group A) gene was previously localized to chromosome 11, region q22-q23. Analysis of the segregation of RFLP markers from this region in a Jewish-Moroccan family assigned to group C indicates that the ATC (A-T complementation group C) gene localizes to chromosome 11q22-q23 as well.

Childhood protein-losing enteropathy associated with Helicobacter pylori infection.
Helicobacter pylori was found in a gastric biopsy specimen of a child with protein-losing gastropathy. Through erythromycin therapy, clinical and ultrasonographic recovery was associated with the disappearance of the pathogen on repeated biopsy. The association of H. pylori with protein-losing gastropathy has been reported only once in children, to our knowledge. Although the causative correlation between the pathogen and the disease has not been proven yet, we suggest that future cases of protein-losing gastropathy be studied for the presence of H. pylori and followed up by ultrasonographic investigation and urea breath test. Appropriate treatment should be given to suspected cases.

Predictive testing for Wilson's disease using tightly linked and flanking DNA markers.
We studied DNA polymorphisms for five new chromosome 13 markers in 52 Wilson's disease (WD) families from Europe, North America, and the Middle East. There was significant evidence for linkage between the Wilson's disease locus (WND) and all the marker loci. Multilocus linkage analysis, using a genetic linkage map established from reference pedigrees, suggested that WND is most likely between D13S31 and D13S59, at distances of 0.4 and 1.2 centimorgans, respectively. Our results suggest that the chromosomal location of the Wilson's disease gene is the same in all families from the populations studied. This evidence and the availability of many close, flanking, and polymorphic DNA markers make possible accurate and informative testing of potential carriers and WD homozygotes in families with at least one previously affected child. An advantage of a genetic linkage test over other laboratory methods for prediction of genotype in WD is that a reliable diagnosis can be made at a much earlier stage in life, including prenatally. In addition, DNA testing can be used in place of an invasive liver biopsy procedure to confirm a diagnosis in patients with borderline serum ceruloplasmin levels. Presymptomatic identification will also allow therapeutic intervention to prevent symptoms before irreparable liver or neurologic damage occurs. We describe the implementation of prenatal and preclinical diagnosis for two families with WD.
